Cistercian Gothic is a style of architecture that emerged in the 12th century, primarily associated with the Cistercian monastic order. It is characterized by its simplicity and functionality, focusing on unadorned structures that reflect the Cistercians' values of austerity and humility. Key features include pointed arches, ribbed vaults, and large windows that allow natural light to illuminate the interiors. This architectural style often emphasizes the use of local materials and a harmonious relationship with the surrounding landscape. Notable examples of Cistercian Gothic include the Abbey of Fontenay in France and the Abbey of Clairvaux, showcasing the blend of spiritual purpose and architectural innovation.
